Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a cable locking device in a connector and a connector. Background Art

[0002] Since the cables in the connector need to be locked to prevent the wires from being displaced during use and affecting the contact of the contact wires, a locking mechanism is often used to lock and position the internal cables.

[0003] There are two main types of locking mechanisms for locking wires in existing connectors. One is a pipe joint, which uses a nut or other structure to tighten or release the end of the bushing to achieve the tightening and loosening of the cable; the other is a wire clamp, which uses a connecting bolt to connect the wire clamps. There are positioning holes between the wire clamps, so that the wire clamps can move closer or farther away from each other to achieve the clamping and release of the cable in the connector. Although both products can play a positioning role in the cable, the pipe joint is expensive, and both methods have high requirements for the diameter of the cable, and cannot adapt to the locking operation of the wire with a large diameter change. That is, when the diameter of the cable in the connector increases or decreases significantly, both methods cannot be well adapted, and multiple adaptation models need to be manufactured for adaptation, which increases the cost of use.

[0004] Therefore, there is an urgent need to provide a cable locking device in a connector and a connector to solve the problems existing in the prior art to a certain extent. Summary of the invention

[0007] Among them, the positioning mechanism includes a positioning assembly, a connecting arm and a pressure plate; one end of the connecting arm is connected to the positioning assembly, and the other end is detachably connected to the pressure plate, the pressure plate and the clamping member are arranged in a one-to-one correspondence, and the adjustment assembly is located between the pressure plate and the clamping member, and the first adjustment member is detachably connected to the pressure plate.

[0008] Specifically, the cable locking device in the connector provided by the present invention also includes a connecting member, a connecting portion is formed on the pressure plate, a connecting hole is formed at one end of the connecting arm, an alignment hole is formed on the connecting portion, and the connecting member passes through the connecting hole and the alignment hole so that the connecting arm and the connecting portion are detachably connected.

[0009] Furthermore, the connecting hole is a waist hole, and the connecting component includes a connecting bolt and a nut, and the connecting bolt passes through the alignment hole and the connecting hole to be connected with the nut.

[0010] Wherein, the positioning assembly includes a positioning rod and a positioning seat; a positioning portion is formed on the positioning seat, the positioning rod passes through the positioning portion and is detachably connected to the positioning seat, and a buckling portion is formed at one end of the connecting arm away from the pressure plate, and the buckling portion is C-shaped and buckled with the positioning rod.

[0011] Specifically, the connection parts on the two pressing plates arranged opposite to each other are staggered, so that the two connection arms connected to the positioning rod are staggered.

[0012] Furthermore, the positioning assembly also includes an elastic member and a handle; the positioning seat includes a first seat body and a second seat body, and the positioning portion of the first seat body and the positioning portion of the second seat body are both formed with through holes, and the positioning rod passes through the through holes and is slidably connected to the first seat body and the second seat body; the handle is connected to one end of the positioning rod facing the first seat body, and the elastic member is arranged between the handle and the first seat body, a matching portion is formed at the other end of the positioning rod, and a locking hole is formed on the second seat body, and the matching portion can enter the locking hole to limit the rotation of the positioning rod.

[0013] Furthermore, the first seat body and the second seat body are both connected with a fitting portion, and a plurality of positioning holes are formed on the fitting portion for mounting the first seat body and the second seat body.

[0014] Furthermore, a sealing ring is sleeved on the positioning rod at a position corresponding to the connecting arm, and the buckling portion is buckled on the sealing ring.

[0015] Compared with the prior art, the cable locking device in the connector provided by the present invention has the following advantages:

[0016] The cable locking device in the connector provided by the present invention comprises a positioning mechanism, an adjusting assembly and a clamping member; the adjusting assembly comprises a first adjusting member, a threaded fastener and a second adjusting member, an adjusting groove is formed along the axial direction of the first adjusting member, and one end of the second adjusting member can move relative to the first adjusting member in the adjusting groove; the threaded fastener can pass through the first adjusting member and lock with the second adjusting member; one end of the first adjusting member away from the second adjusting member is connected to the positioning mechanism, and one end of the first adjusting member away from the second adjusting member is connected to the clamping member, there are at least two clamping members, and the two clamping members are arranged relative to each other to form a clamping space.

[0017] From this analysis, it can be seen that by connecting the first adjusting member to the positioning assembly, and connecting the second adjusting member to the clamping member, and there are at least two clamping members in the present application, a stable clamping space can be formed to achieve clamping of the cable.

[0018] When the cable model changes and the diameter changes, since the first adjustment member in the present application is formed with an adjustment groove extending in the axial direction, one end of the second adjustment member can be inserted into the adjustment groove, and the first adjustment member and the second adjustment member can move relative to each other. Therefore, through the relative movement of the first adjustment member and the second adjustment member, the length of the overall adjustment component can be changed, so that the distance between the two relatively arranged clamping members can be changed. When the cable diameter increases, the distance between the two clamping members can be increased by shortening the overall length of the first adjustment member and the second adjustment member, so as to adapt to cables with larger diameters. Correspondingly, when the cable diameter decreases, the distance between the two clamping members can be reduced by increasing the overall length of the first adjustment member and the second adjustment member, so as to adapt to cables with small diameters. Therefore, the adjustment component can effectively increase the adaptation range of the cable diameter, and there is no need to manufacture multiple types of cable locking devices in connectors, thereby reducing the cost of use.

[0020] The connector using the cable locking device in the connector provided by the present application has a higher adaptability to the cable, and a set of devices can adapt to cables of different diameters, so there is no need to develop other types of cable locking devices in the connector, which greatly reduces the difficulty of selection and production costs. It can be understood that since the cable in the present application is located in the shell, the positioning assembly in the present application is connected to the shell, and a corresponding avoidance groove is formed on the shell for positioning the pressure plate, and a mounting portion is formed in the area of ​​the avoidance groove, and a mounting hole is formed on the mounting portion, so that one end of the second adjustment member can pass through the mounting hole to connect with the first adjustment member.

[0037] like Figure 1 Combination Figure 2 and Figure 4 As shown, the present invention provides a cable locking device in a connector, comprising a positioning mechanism, an adjustment assembly and a clamping member 1; the adjustment assembly comprises a first adjustment member 2, a threaded fastener and a second adjustment member 3, an adjustment groove is formed along the axial direction of the first adjustment member 2, one end of the second adjustment member 3 can move relative to the first adjustment member 2 in the adjustment groove; the threaded fastener can pass through the first adjustment member 2 and lock with the second adjustment member 3; the end of the first adjustment member 2 away from the second adjustment member 3 is connected to the positioning mechanism, and the end of the first adjustment member 2 away from the second adjustment member 3 is connected to the clamping member 1, there are at least two clamping members 1, and the two clamping members 1 are arranged opposite to each other to form a clamping space.

[0038] Compared with the prior art, the cable locking device in the connector provided by the present invention has the following advantages:

[0039] The cable locking device in the connector provided by the present invention is connected to the positioning assembly through the first adjusting member 2, and the second adjusting member 3 is connected to the clamping member 1, and there are at least two clamping members 1 in the present application, so as to form a stable clamping space and achieve clamping of the cable 15.

[0040] When the cable 15 model changes and the diameter changes, since the first adjustment member 2 in the present application is formed with an adjustment groove extending in the axial direction, one end of the second adjustment member 3 can be inserted into the adjustment groove, and the first adjustment member 2 and the second adjustment member 3 can move relative to each other. Therefore, through the relative movement of the first adjustment member 2 and the second adjustment member 3, the change of the length of the overall adjustment assembly can be achieved, so that the distance between the two relatively arranged clamping members 1 can be changed. Then, when the diameter of the cable 15 increases, by shortening the overall length of the first adjustment member 2 and the second adjustment member 3, the distance between the two clamping members 1 can be increased to adapt to a cable 15 with a larger diameter. Correspondingly, when the diameter of the cable 15 decreases, the distance between the two clamping members 1 can be reduced to adapt to a cable 15 with a small diameter by increasing the overall length of the first adjustment member 2 and the second adjustment member 3. Therefore, the adjustment assembly can effectively increase the adaptation range of the diameter of the cable 15, without the need to manufacture multiple types of cable locking devices in the connector, thereby reducing the cost of use.

[0041] It should be noted that the threaded fastener in the present application is a set screw, and a screw hole is formed on the first adjusting member 2 and penetrates the wall of the first adjusting member 2 in the radial direction, and the screw hole is connected with the adjusting groove, so that the set screw can pass through the screw hole and abut against the second adjusting member 3 to achieve locking of the second adjusting member 3. In the present application, the second adjusting member 3 is formed with a plug-in portion 301, which can be inserted into the adjusting groove, and the set screw passes through the wall of the first adjusting member 2 and abuts against the plug-in portion 301 to achieve locking.

[0042] It needs to be further explained here that, in the present application, the connection between the first adjusting member 2 and the positioning assembly and the connection between the second adjusting member 3 and the clamping member 1 can be achieved by threaded connection, that is, in the present application, the outer wall surface of the end of the first adjusting member 2 away from the second adjusting member 3 and the outer wall surface of the end of the second adjusting member 3 away from the first adjusting member 2 are both formed with threaded portions, and accordingly, screw holes are formed at corresponding positions of the clamping member 1 and the pressure plate 4 described below, thereby enabling the first adjusting member 2 to be detachably connected to the pressure plate 4, and the second adjusting member 3 to be detachably connected to the clamping member 1.

[0043] During installation, first place the clamping member 1 into the connector housing 14 described below, then pass the first adjusting member 2 through the housing 14 and connect it to the clamping member 1, and at the same time connect the second adjusting member 3 to the external pressure plate 4, and finally, insert the plug-in portion 301 of the first adjusting member 2 into the adjustment groove of the second adjusting member 3, and use threaded fasteners to lock the relative positions of the first adjusting member 2 and the second adjusting member 3 to complete the installation.

[0044] When threading, since the diameter of the cable 15 has a corresponding size according to the model, the distance between the two clamping members 1 can be adjusted according to the corresponding size, and then the cable 15 is passed through, and finally the threaded fastener is tightened to complete the locking.

[0045] Alternatively, if Figure 1 As shown, the positioning mechanism in the present application includes a positioning assembly, a connecting arm 5 and a pressure plate 4; one end of the connecting arm 5 is connected to the positioning assembly, and the other end is detachably connected to the pressure plate 4, the pressure plate 4 and the clamping member 1 are arranged one by one, and the adjustment assembly is located between the pressure plate 4 and the clamping member 1, and the first adjustment member 2 is detachably connected to the pressure plate 4.

[0046] The positioning assembly in the present application is installed on the shell 14 of the connector described below, and the positioning assembly can be connected to the pressure plate 4 through the connecting arm 5. Moreover, one end of the connecting arm 5 in the present application is detachably connected to the positioning assembly, and the other end is detachably connected to the pressure plate 4, which can realize the adjustment of the angle between the connecting arm 5 and the pressure plate 4, that is, the connecting arm 5 and the pressure plate 4 are rotatably connected. Therefore, the position adjustment of the pressure plate 4 can be realized by rotating the connecting arm 5 relative to the pressure plate 4.

[0047] That is, when locking the wire, the distance between the two clamping members 1 is first adjusted by the first adjusting member 2 and the second adjusting member 3, and the adjustment process can make the distance between the final clamping members 1 match the diameter of the cable 15. After the first adjusting member 2 and the second adjusting member 3 are adjusted, the cable 15 is passed through the clamping space, and then pressure is continuously applied to the pressing plate 4. Since the end of the connecting arm 5 away from the positioning assembly can rotate relative to the pressing plate 4, the clamping member 1 can fit the cable 15. Finally, the connecting end of the connecting arm 5 and the pressing plate 4 is locked to achieve the fixation of the position between the connecting arm 5 and the pressing plate 4, thereby achieving the fixation of the position of the pressing plate 4 through the connecting arm 5, and then completing the action of locking the cable 15.

[0048] It can be understood that in the present application, the pressure plate 4 has two connection positions, so that the two connection arms 5 can be connected accordingly, that is, Figure 1 The upper and lower connecting arms 5 are shown, and through the two connecting arms 5, after being fixedly connected with the pressing plate 4, the position of the pressing plate 4 can be fixed, thereby locking the cable 15.

[0049] Alternatively, if Figure 1 As shown, the cable locking device in the connector provided by the present invention also includes a connecting member, a connecting portion 401 is formed on the pressure plate 4, a connecting hole 501 is formed at one end of the connecting arm 5, and an alignment hole is formed on the connecting portion 401. The connecting member passes through the connecting hole 501 and the alignment hole, so that the connecting arm 5 and the connecting portion 401 are detachably connected.

[0050] The connecting components in the present application are connecting bolts 12 and nuts 13. During the adjustment process, the distance between the connecting bolts 12 and the nuts 13 is greater than the total thickness of the connecting arm 5 and the connecting part 401, so that the connecting arm 5 and the connecting part 401 can rotate relative to each other, thereby achieving the adjustment of the position of the pressure plate 4.

[0051] When the adjustment is completed, the connection bolt 12 and the nut 13 can be locked to fix the position of the connection part 401 and the connection arm 5, thereby fixing the position of the clamping member 1 and further locking the cable 15.

[0052] Preferably, if Figure 1 Combination Figure 5 As shown, the connection hole 501 in the present application is a waist hole, so that the position change between the connection arm 5 and the connection part 401 can be achieved.

[0053] Alternatively, if Figure 1 Combination Figure 5 As shown, the positioning assembly in the present application includes a positioning rod 6 and a positioning seat; a positioning portion 701 is formed on the positioning seat, the positioning rod 6 passes through the positioning portion 701 and is detachably connected to the positioning seat, and a buckling portion 502 is formed at one end of the connecting arm 5 away from the pressure plate 4, and the buckling portion 502 is C-shaped and buckled with the positioning rod 6.

[0054] The positioning seat in the present application is connected to the housing 14 of the connector to provide positioning for the overall structure. By passing the positioning rod 6 through the positioning seat, a basis for the connection of the connecting arm 5 can be provided. By forming a C-shaped snap-fit ​​portion 502 at one end of the connecting arm 5 away from the pressure plate 4, the connection between the connecting arm 5 and the positioning rod 6 can be made faster.

[0055] During adjustment, continuously apply pressure to the pressure plate 4 to pre-lock the relative position of the connecting arm 5 and the connecting portion 401, then assemble the buckle portion 502 on the positioning rod 6, and completely lock the connecting member to fix the overall structure.

[0056] Alternatively, if Figure 1 Combination Figure 3 As shown, the connection parts 401 on the two pressing plates 4 arranged opposite to each other in the present application are offset, so that the two connection arms 5 connected to the positioning rod 6 are offset.

[0057] Since two connecting arms 5 are connected to the same connecting rod, in order to ensure that the connecting arms 5 can be connected smoothly, the connecting parts 401 on the two opposite pressure plates 4 in the present application are staggered, so that the connection positions of the connecting arms 5 on the positioning rod 6 can be staggered to avoid mutual interference.

[0058] Alternatively, if Figure 1 Combination Figure 3 As shown, the positioning assembly also includes an elastic member 9 and a handle 10; the positioning seat includes a first seat body 7 and a second seat body 8, and the positioning portion 701 of the first seat body 7 and the positioning portion 701 of the second seat body 8 are both formed with through holes, and the positioning rod 6 passes through the through holes and is slidably connected with the first seat body 7 and the second seat body 8; the handle 10 is connected to one end of the positioning rod 6 facing the first seat body 7, and the elastic member 9 is arranged between the handle 10 and the first seat body 7, a matching portion 601 is formed at the other end of the positioning rod 6, and a locking hole 801 is formed on the second seat body 8, and the matching portion 601 can enter the locking hole 801 to limit the rotation of the positioning rod 6.

[0059] like Figure 1 As shown, the locking hole 801 in the present application is connected with the through hole on the second seat body 8, and the locking hole 801 is located on both sides of the through hole, and the width is smaller than the diameter of the through hole, and the matching portion 601 is formed by the end of the positioning rod 6, and a T-shaped structure is formed between the matching portion 601 in the present application and the positioning rod 6, so that when the matching portion 601 is embedded in the through hole, the positioning rod 6 can be limited to prevent the positioning rod 6 from rotating.

[0060] Since an elastic member 9 is provided between the first seat body 7 and the handle 10 in the present application, when the operating handle 10 drives the positioning rod 6 to rotate and the matching portion 601 rotates to the corresponding position of the locking hole 801, the elastic member 9 rebounds and drives the handle 10 to move away from the first seat body 7, so that the matching portion 601 can be embedded in the locking hole 801, thereby realizing the rotation limitation of the positioning rod 6.

[0061] After the positioning rod 6 is locked, the buckling portion 502 of the connecting arm 5 is buckled onto the positioning rod 6 to achieve the connection between the connecting arm 5 and the positioning rod 6. Finally, the connecting bolt 12 and the nut 13 are tightened to achieve the locking of the overall structure.

[0062] Preferably, if Figure 1 Combination Figure 5 As shown, a sealing ring 11 is sleeved on the position of the positioning rod 6 corresponding to the connecting arm 5 in the present application, and the buckling portion 502 is buckled on the sealing ring 11 .

[0063] In actual operation, when the operating handle 10 is rotated to make the matching portion 601 correspond to the locking hole 801, the elastic member 9 can be resiliently inserted into the locking hole 801. Accordingly, the sealing ring 11 sleeved on the positioning rod 6 can move to a position corresponding to the connecting arm 5. Through the buckling of the buckling portion 502 and the sealing ring 11, a stable connection between the connecting arm 5 and the positioning rod 6 can be achieved.

[0064] When the wire needs to be removed, the handle 10 is first pushed to move the matching portion 601 away from the locking hole 801, and then the handle 10 is rotated to displace the matching portion 601 from the locking hole 801. At this time, the elastic member 9 is compressed, and the sealing ring 11 is offset from the connecting arm 5, so that there is a certain amount of movement space between the connecting arm 5 and the positioning rod 6, and the cable 15 is initially loosened. After that, the connecting bolt 12 and the nut 13 are loosened to loosen the connecting arm 5 and the pressure plate 4, thereby expanding the clamping space and completing the release of the cable 15.

[0065] It is understandable that when the cable 15 needs to be further released, the threaded fastener can be loosened to allow the first adjusting member 2 and the second adjusting member 3 to move relative to each other, thereby achieving further release of the cable 15 .

[0066] Alternatively, if Figure 1 As shown, the first seat body 7 and the second seat body 8 in the present application are both connected with a fitting portion 702 , and a plurality of positioning holes are formed on the fitting portion 702 for mounting the first seat body 7 and the second seat body 8 .

[0067] The fitting portion 702 in the present application fits with the outer wall surface of the housing 14, thereby providing a stable installation base for the first seat body 7 and the second seat body 8. Accordingly, through the multiple positioning holes formed on the fitting portion 702, positioning bolts can be installed corresponding to the positioning holes, thereby realizing a detachable connection between the fitting portion 702 and the housing 14.

[0068] In addition, the present invention also provides a connector, including a shell 14, a cable 15 and the above-mentioned cable locking device in the connector; an avoidance groove is formed on the shell 14, an installation portion is formed in the area of ​​the avoidance groove, a mounting hole is formed on the installation portion, one end of the second adjustment member 3 passes through the mounting hole and enters the adjustment groove; the pressure plate 4 is embedded in the avoidance groove; the cable 15 is located in the clamping space.

[0069] The connector using the cable locking device in the connector provided by the present application has a higher adaptability to the cable 15, and a set of devices can adapt to cables 15 of different diameters, so there is no need to develop other types of cable locking devices in the connector, which greatly reduces the difficulty of selection and production costs. It can be understood that since the cable 15 in the present application is located in the shell 14, the positioning assembly in the present application is connected to the shell 14, and a corresponding avoidance groove is formed on the shell 14 for positioning the pressure plate 4, and a mounting portion is formed in the area of ​​the avoidance groove, and a mounting hole is formed on the mounting portion, so that one end of the second adjustment member 3 can pass through the mounting hole to connect with the first adjustment member 2.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
